Abstract

A display device includes a display member configured to display an image in a first direction and a cover member on the display member. The cover member includes a flexible member including a front part defining a front plane perpendicular to the first direction, and a first side part connected to a first side of the front part and defining a first side plane different from the front plane, and a rigid member partially overlapping the flexible member and on the front part.

First claim

What is claimed is:

1. A method of manufacturing a cover member, the method comprising:
providing a lower mold defining a first inner space;
providing a rigid member formed of glass in the first inner space, the rigid member comprising a first rigid member and a second rigid member offset from the first rigid member, the first and second rigid members defining a gap therebetween;
providing an upper mold on the lower mold to define a second inner space different from the first inner space;
injecting a liquid polymer into the second inner space including the gap between the first and second rigid members;
curing the liquid polymer to form the cover member, the cover member being a window of a display device; and
separating the cover member from the upper and lower molds,
wherein an upper surface of the rigid member is exposed to the second inner space, and the liquid polymer covers an entirety of the upper surface of the rigid member,
wherein the first inner space is defined by a planar surface of the lower mold and side surfaces bent from the planar surface in a first direction to surround the planar surface, and
wherein the first rigid member is on the planar surface and the second rigid member is on one of the side surfaces.

2. The method of claim 1 , wherein the rigid member further comprises:
a third rigid member on one of the side surfaces facing the one of the side surfaces on which the second rigid member is located.

3. The method of claim 2 , wherein each of the first and second rigid members comprises:
a first surface configured to contact the lower mold,
a second surface opposite to the first surface, and
a plurality of connection surfaces configured to connect the first surface to the second surface, and
wherein the liquid polymer is injected into the second inner space to contact the second surface and the connection surfaces.

4. The method of claim 3 , wherein the liquid polymer is filled into a region of the second inner space around the rigid members.

5. The method of claim 4 , wherein a shape of the cover member corresponds to that of the second inner space.

6. A method of manufacturing a cover member, the method comprising:
providing a plurality of rigid members formed of a transparent material and offset from one another, the plurality of rigid members defining a gap therebetween;
forming a flexible member comprising:
a plane part defining a first recess part;
a first bent part bent from a first side of the plane part in a first direction and defining a second recess part; and
a second bent part bent from a second side of the plane part in the first direction, the second bent part defining a third recess part;
a portion configured to fill the gap of the plurality of rigid members; and

coupling the plurality of rigid members to the first, second, and third recess parts to form the cover member, the cover member being a window of a display device.

7. The method of claim 6 , wherein the flexible member is formed by injection-molding a polymer.

8. The method of claim 7 , wherein each of the first and second recess parts has a depth that is substantially the same as a thickness of each of the plurality of rigid members.
